HARRY BRADWELL, OEKEIGHLEY, ENGLAND.

WRAPPING MACHINE.

Application filed December 12, 1912.

To all whom it may concern Be it known that I, HARRY BRADWELL, a subject of the King of Great Britain, residing at Keighley, in the county of York, England, have invented a new and useful Improvement in WVrapping-Machines, of which the following is a specification.

This invention relates to improvements in machines or apparatus for wrapping tofi'ee, caramels, chocolates, and other sweetmeats and the like articles in paper covers, the ends of which are to be twisted to retain them in position, and my present invention consists in the production of a new or improved machine or apparatus for this purose. I p According to my invention, the paper for wrapping purposes is first fed from a roll and a portion suilicient for the Wrapping of one article subsequently severed or cut off. The wrapper is suitably supported in position over a plate carried by a rod radially disposed in an intermittently rotated disk.

The article to be wrapped is supplied from a magazine by being pressed through the outlet on to the wrapper and together with the wrapper into a recess or the like formed in the periphery ofsaid disk, where itis held during the subsequentfohling and twisting operations. The pressing down of the article into said recess causes the free ends or sides of the wrapping paper to assume approximately vertical positions, when they are folded over the article by a cam operated lever and by the disk on the next forward feed. Thismovcment or feed of the disk is also such as to bring the article with the loose ends of the wrapper into a position opposite two pairs of twisting jaws which subsequently seize and twist the said ends in the desired manner for effectually inclosing or pareeling the article. The continued rotation of the parceling disk enables the package to be conveniently discharged into a tray, conveyor or the like for removal.

T he particular construction and arrangement of the mechanism and the movements necessary for performing the operations are such as to insure a continued and auton'latic performance.

Description of drawings: Figure 1 is a plan view of my improved machine or apparatus for wrapping toil'ee, carainels. chocolates, and other sweetmeats and the like. Fig. 2 is a sectional side elevation of part of apparatus shown at Fig. 1. Fig. 3 1s a Specification of Letters Patent.

Similar letters and figures refer to similar parts throughout the several views.

In carrying this invention into effect, I employ suitable standards or supports A suitably secured upon the machine table H, and mount therein. a con enient shaft A carrying a roller B having a gripping surface in connection with which operates another similar roller C mounted in resilient bearings D so that it exercises a continuous pressure .upon said roller B. The roller B projects through a slot 13 in a feed table B also carried by the standards A, with its periphery slightly above the surface of said table. Between these two rollers over the table B is fed the paper E for wrapping purposes from a roll F which is placed in bearings G also secured to thetable H or in any other convenient position in or in proximity to the machine, such feeding of the paper being intermittently performed in order that the requisite amount of paper for wrapping one of the articles to be parceled fed forward to appropriate supports or holders J, J. The feed is effected by a pinion K upon the shaft A, gear wheels L, L,

shaft M, ratchet N, ratchet Wheel P, levers R, R, and connecting rod S, operated by the cam T on the main driving shaft U see lfig;= 6. This paper on being fed forward by the rollers B C, is automatically operated upon by a knife V mounted upon a shaft W' movable in hearings in the standard A by lever X and cam T, the latter also keyed on shaft U, by which means a portion thereof, suflicient for the Wrapping of one article is severed or cut ofi' on the termination of each feed.

in suitable proximity to the parts J upon Which the paper is fed, see F g. 2, 1s mounted the magazine for supplying the articles to be Wrapped, Which preferably consists of a fixed flanged disk or plate 1, and above or Within this fixed plate and in close proximity thereto is arranged another plate 2 having recesses, notches, or serrations 3 near or in itsouter edge. Thls serrated plate is also intermittently moved suflicient to bring the next space or serra- Jtion immediately over the outlet or chute 4 in the plate 1. The plate 2 is mounted upon a flanged sleeve 5 fitting a vertical studor shaft, and is given the necessary rotation by ratchet 7 pivoting upon a lever 8 eperated by a earn 9 upon the shaft 10, actuating the ratchet Wheel 6. The number of articles to be Wrapped are placed in position between or inthese serrations to rest upon the fixed disk 1 below, and the number of teeth in the "Wheel 6 preferably corresponds With the number of spaces in the Wheel 2, so that the movement of said Wheel 6 the space of one tooth is synonymous With the movement of the Wheel 2 for feeding another article to the Wrapping device hereinafter described. The shaft 10 is driven by chain 11 and chain Wheels 12 from the main shaft U. I

As each article enters the chute it comes in contact With and is held by suitable spring jaws 13 ivhile the paper is moved into position and a portion cut oft, The jaws are of separate construction secured to a bracket 13*, and the lower jaw prmects farther than the upper jaw in order to cope with any unevenness in size of the article to be treated. l-Vhen the paper Wrapper has been out off, a plunger or finger ls secured to one end of a vertical shaft sliding Within a suitable bearing 16, is operated by a spring 17, or by a. cam actuated lever, to ress each article through the outlet at on to e paper Wrapper and together with the 'rapper against a plate or hea 8 carried piston or rod 19 operating between jaw 20 and a sliding jav and re. dially disposed in a disk 22, which is ntermitt ntly rotated simultaneously with. and T i shaft ill aforesaid 2. is controll d l open 1'1: but the jaw is allowed to close on saidarticle in order to prevent it shifting its position on the Withdrawal of the plunger by the lever 17 and earn 17 which act in opposition to the spring 17, and to so hold the same during the subsequent folding and twisting operations, see Figs. 7 and 8. The Wrapping paper at this stage Will partially surround the article With the free sides extending somewhat in a vertical direction, see also Fig. 13. I

To fold the sides of the Wrapper over the said article I employ a plate 26 mounted upon a pivoted lever 27 also operated by a suitable cam 22 on shaft U. This plate see Fig. 9 lays one free side of the Wrapper on the top of the article While the other side is folded to overlap this, one, as shown at Figs. 15 and 16, by the next operation of the dish 22. The disk 22 in being rotated an appropriate distance brings the unfolded portion of the Wrapper againstthe edge of one of the plates J which turns it down as aforesaid, and it is so held by a spring plate or cover all during the rest of the feed movement of said disk and the subsequent twisting of the free ends of same. At the termination of theaforesaid feed the partially wrapped article is brought into a position opposite two pairs of javvs or grippers which are capable of both rotary or oscillating movements anda movement longitudinally of their bearings.

Each pair of or grippers 29 are fixed upon a shaft mounted in suitable bearings 35 situated upon each side of the disk 22 and at right angles to the same; said are automatically actuated in the direction for opening them by means of pivoted lever-s30 operated by cams 31 on the shaft 10, While they are closed on the return of said levers, by the springs 32 or other suitable means. Their oscillating motions are preferably effected by means of quadrants gearing With pinions 34 mounted on the shafts 35 aforesaid, said quadrants being reciprocated in any appropriate manner such as by being mounted upon a common shaft or pivot 36 with an arm 3? cperated by earn on the shaft ll, While their longitudinal movements also effected from said shaft by cam 39 actuating levers or arms 4:0, ll lreyed t E2, the end of 12ft lever ll operating Within a necl: 4&3 upon each shaft Their actions are such that on the dish 22 bringing the partially d 'icle to a po ion opposite these shai '"ter, vv he jaws opened moved longitudinally of their bearings toward said article, are in such a position that the now open jaws surround or partially surround the ends of the wrapping paper, when said jaws released by the springs 30 acting on levers 30, are closed by the springs 32 and lay hold of the ends of said paper so that the rotation ofthe said shafts by the quadrants will twist said ends in the manner desired for effectually retaining or inclosing the articles under treatment. The rotation of the shafts for twisting purposes occurs before the completion of the longitudinal movement, so that the latter may compensate for the shortening of the package and prevent fracture of the wrapper durin such twisting operation. Upon the comp etlon of the twisting operation and immediately preceding the return of the shafts by the levers 40, 41, actuated by the springs 35 the jaws are again -opened to release the package by the cam projection 45 on the cams 3l operating on the levers 30. Th1s release of the package occurs immediately precedin the next operation of the disk 22.

Instead of transmitting oscillating'mo tionto the shafts carrying the grippersas above described, I may transmit thereto intermittent rotary motion, and this latter may, if desired, by appropriate gearing be obtained from any of the shafts 1n the machine which move intermittently, or ratchet and wheel, or other mechanism may be employed for this purpose.

The jaws are preferably provided with an india rubber or similar pad or lining 46 which enables them to more effectually lay hold of the ends of the wrapper, and all the cam operated levers are where necessary returnable by springs, weights, or the like.

The continued rotation of the disk 22 car- .ries the article or package underneath or to the lowest point in said disk where it is dislodged by a lever 47 actuated by a cam 48 upon the shaft 10, or by a fixed cam surface acting on said piston rod 19 sliding same in its bearings 49 formed by a swell on the sideof the aforesaid disk, until the package is pressed out of the grip of the jaw 21 when it may drop into an appropriate receptacle or upon a traveling belt, band or the like, so as to be packed or transferred to any part desired. The rod 19 is also controlled in its movement by the pressure of a spring 50, or by other suitable means, and the disk 22 may be provided with several pairs of jaws or receptacles according to the speed at which it is driven relatively with the speed of the other parts of the machine. Further, the disk or wheel 22 and the serrated Wheel 2 of the magazine are each provided with a suitable brake no shown, for governing their movements.

The action of the apparatus is as follows :-At the commencement of operations the paper sheet E is fed forward to the position shown at Fig. 2, by the rollers B C, the knife V then comes into operation and cuts off a portion which serves as a wrapper -for the next article to be treated. The wheel 2 is now moved to feed said article to the chute 4 where it is temporarily held by the jaws 13. The plunger now descends and presses the article down on to the wrapper and against the plate 18 until both article and wrapper are within a recess formed by the jaws 20 and 21 in the disk or wheel 22, the jaw 21. having been moved back against the spring 23 to allow of easy access. Be fore the plunger is withdrawn however the jaw 21 is released, gripping the partially wrapped article and holding same during such withdrawal see Fig. 8, and later until it is dislodged from the machine a complete package. Immediately following the withdrawal of the plunger 14 one of the free sides of the wrapper is laid by the plate 26 see Fig. 9, and the other side by the plate J during the next operation of the disk 22 which is synonymous with the next feed of the sheet for the next package. The article on the said next feed is'brought opposite the twisting jaws 29 see Fig. 10, which operate to seize and twist the free ends of the wrapper to complete the package; meanwhile a second article has been introduced to the wrapping mechanism so that on the third feed operation the first article completely wrapped or parcelecl is released by the twisting jaws and the second package brought into position for having its open ends twisted, while a third article is now introduced to the wrapping mechanism, and so on until during the twisting of the third package the first package is pressed out of the disk 22 into a receptacle, conveyor or the like for removal. These operations are continued until as each article to be wrapped is introduced to the wrapping mechanism, a completed package is discharged therefrom, the output being limited by the/cw pacity of the apparatus or the speed at which it may be driven.

All the cams are arranged to operate upon the several levers at the proper time to insure an accurate, continuous and automatic performance of the operations necessary in wrapping or parceling toli'ee or other suit able goods.

The machine may be duplicated and operate in series, and may be rotated by means of driving belts, an electric motor or the like, and where desired or necessary appropriate clutch mechanism may be employed for governing the stopping and starting of the rotary motion thereof.

In the apparatus above described where sweets or confectionery are being wrapped or parceled it may be necessary that they should be fed to the magazine by hand owing to their sticky or adhesive nature; how ever when other articles such as spools or carriers for silk or somewhat similar goods are to be operated upon, then I may arrange these to be automatically fed through a hopper, chute, or other device or to a disk or the like provided with appropriately shaped openings or serrations somewhat in the manner above referred to.
